It can be used in various types of food safety testing, agricultural product residue monitoring, medical and hygiene, environmental protection, commodity inspection, tap water and chemical production laboratory.

Instrument introduction: CNC solid phase extraction instrument fully supports each step of solid phase extraction operation, accurately controls the flow rate of various solutions through columns in a CNC manner, and also has positive pressure elution, large volume continuous injection and timing functions to ensure the recovery and purity of the target analytical substance, reduce relative deviations, and avoid cross-contamination between samples. Multiple samples can be processed at the same time, further improve work efficiency, and easy operation and maintenance. Its general principle is to use the counting of CNC pumps. Each column joint can independently provide a relatively constant negative pressure. All solutions can pass through the columns according to the flow rate required by the standard analysis procedure, ensuring efficient extraction of the target analytical substances. Finally, the columns are converted to the elution rack, and the positive pressure is elution at a constant speed to avoid cross-contamination.

Main features:

1.Accurate speed control, single-channel flow rate 0.01-7 ml/min， Supports large volume injection and positive pressure elution to avoid cross-contamination；
2.Stepless CNC operation, LED Digital display, the flow rate can be determined by digital display, and the flow rate can be determined, and the timing function is；
3.Multi-channel, small column joints are resistant to acid, alkali, organic solvents, and oxidant corrosion；
4.Simple operation, single operation can handle 1-8 samples at the same time, greatly improving work efficiency；
5.Good extraction speed consistency and easy control and adjustment；
6.Good sealing, strong stability, and good linear relationship between rotation speed and flow rate.
